To all whom t may concern: Y

Be it known that I, URIAH L. BARNES, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Transmission Mechanism and Casings, of which the ation of iny 1:xiiplication' for transmission mechanism, October 2, 1917, Serial No. 194,365, and the objects of my invention, are: first, to provide a three-speed transmission mechanism that is so. constructed that it will t into the ordinary Ford transmission casing and replace the ordinary plane;

tary transmission; second, to provide a three-speed transmission mechanism of compact form to be used in connection with said casing; third, to provide a combined mechanism and easing of this class which is simple and economical of construction, durable, easy to install in the place of the ordinary planetary transmission casing, easy to op-` erate and which will not readily deteriorate or get out of order.

With these and other objects in view as will appearhereinafter-my invention consists of certain novel features of construetion, combination and arrangementof parts as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this specication, in which: f

Figure 1 is a fragmentary sectional view of the ordinary Ford transmission. casing showing my casing'therein in section and showing the transmission mechanism therein, partly in elevationiand partly. in section, to facilitate the illustration: Fig.. 2, is a bottom view of my transmission casing: Fig.A 3, is a top-view of the intermediate section of said casing: Fig. 4 is a sectional view through 4-4 of Figs. 1, 2, 3 and 5, and Fig. 5 is a top view of the cover plate which ed on this s iits over the hole in the upper side of the ordinary Ford transmission casing.

Similar characters of reference referto similar parts throughout the several views of the drawings. v

riihe casing members 1, 2, and 8, counter shaft 4, gear 5, gear 6, gear 7, spacers 8,

rear drive shaft 9, low and reverse sliding gear 10, high and intermediate gear 11, high and main drive gear 12, front drive shaft 13, bearings 14, 15, 16, and 17 casing cover 20, reverse gear 2l, reverse pinion 22, counter shaftand'plate 23, counter shaft end plate24, and shifting lever 25, constitute the principal parts of my transmission mechanism and casing.

The casing member l is shaped as shown best in Figsfl, 2, and@ of the drawings. It is provided with outwardly extending flanges 1a adapted to rest on the top edge of the lower half ofthe conventional transmission casing and be secured thereto by bolts through the holes 1b and secured on ythe top of this casing member 1 is an intermediate casing 2 and mounted on the top of the intermediate casing'2 is the upper casing member 3. Mounted between the casing members 1 and 2 are the bearings 15 and 16 in which are revolubly mounted the shafts 9 and 13. The shaft 9 is provided on its one end with an enlarged portion 9a which is `10 is provided with a hub on one side in which is a groove 10 adapted for a shifting lever which extends to a recess 1c in the casing 1 where it is engaged by the lever 25 for shifting the ear 10 on the shaft 9. Mounthaft 9 is also another gear 11 which is provided with an extended hub portion on one side in which is rovidedy a groove 11* adapted for Aa shi ting lever which extends to the recess 1 in the casing 1, where it is engaged by said lever 25. Mounted onv this extended hub portion is the clutch member 11b which is adapted to engage a clutch member 12l secured to the gear 12 on the shaft 13. rlhis gear 12 is secured to the end'of the shaft 13 while the gears 10 and 11 are shiftably mounted longitudinally on the shaft 9 and are held from turning thereon by means of keys. It will be here noted th'at the shaft 13 extends into the shaft 9. '.Mounted between the casing members 2, and 3 is the counter shaft 4 parallel with the shaft 9 in bearings 14land 17 and secured 0n said shaft is a large gear 5 in alinement with and engaging the gear 12 and secured to said shaft 4 is another gear-.6 which is the intermediate gear that engages the gear 11 when it is shifted in one direction. Also secured to this shaft 4 is the low speed gear 7 which is adapted to engage the gear 10 when said gear 10 is shifted to the proper relative position, for producing the low speed. On this shaft 4 is also secured the reverse gear 21 which engages an idler pinion 22 which is supported on a shaft 22a which is journaled on a lug bearing 2"L extending inwardly on the casing2 as shown best in Fig. 4 of the drawings. This pinion 22 is also adapted to engage with the gear 10 when the gear 10 is shifted into alinement therewith and produces the reverse Ymovement of the shaftv 9. Pivotally mounted in the casing 3 and cover plate 20 is a lever 25 and this cover plate 2O is secured over the top hole -in the conventional transmission casing. i This lever 25V extends downwardly and engages the shifting levers for shifting the gears 10 and 11. In order to hold the shafts and bearin s in the transmission there are provided p ates 23 and'24 which are secured against the outer surface of the casing for such purpose.4

The operation of my transmission mechanism is as follows: The shaft 13 is conment with the.pinion 22; when it is desired to operate in the intermediate the gear 10 is positioned as shown and the gear 11 is shifted into engagement with the gear 6; when it is desired to operate "in the high reame@ speed the gear 11 is shifted sothat the clutch member 12a on the gear 12 engages the clutch member 11b on the gear 11 and the shaft 9 is driven directly through the clutch in the high speed.

Though I have vshown and described a particular construction, combination and arrangement of parts I do not wish to be limited to this particular construction, combination and-arrangement but desire to include in the purview of my invention the y construction, combination and arrangement substantially as set forth in the appended claims.

ters Patent, is:

1.- ln a transmission mechanism, the combination with a conventional planetary transmission casing, of a casing adapted to fit inside of said conventional casing, change speed gears operatively mounted therein and means for shifting'portions of said gears.

2. lin a transmission mechanismythe com bination with the conventional planetary transmission casing, of a casing adapted to fit inside of said conventional casing, change speed gears operatively mounted therein and means for shifting portions of said gears, extending out through the upperside of said casmg.

3. ln a transmission mechanism, the combination with a conventional planetary transmission casing, of an auxiliary threemember transmission casing adapted to be secured therein and supported thereby'and a three-speed and reverse gear transmission f mounted therein.

4. In a transmission mechanism, the combination with a conventional planetary transmission casing, of van auxiliary three-member transmission casing adapted to be secured therein and supported thereby, a threespeed and reverse gear transmission mounted therein and ball-bearing means mounted between the several sections of said casing and supporting said three-speed and reverse gear transmission.

1n testimony whereof, I have hereunto set my hand at San Diego, California this 6th day of March, 1918.

URIAH L. BARNES.
